During the Q&A session, Piers presented Caitlyn with an old doll of her as Bruce which was released in the wake of his 1976 decathlon victory at the Montreal Olympic Games. "Obviously, certain areas we know about..."

Addressing the current state of his relationship with the children his ex-wife welcomed with her late husband Robert Kardashian, she explained: 'I just don't communicate with them like I used to. "You just said, 'Certain areas?' That to a trans person is disrespectful". "And there was no reason for them to know about it", she confessed. 'I even dressed up with her.

"Despite transitioning over two years ago, the "I Am Cait" star feels there is still a part of her old self within her. It's life. It's part of my life and it's a very serious part of my life".

According to the Evening Standard, Ms Jenner went on to say: "The only ones I'm really concerned about are Kendall and Kylie, yeah they are biological kids".

"It's something, as I said before - this is serious stuff, people die over these issues".

While it's tough to see an otherwise tight-knit family going through a rough time, the KKW Beauty founder assured fans over the summer that, in time, it'll get worked out.

While Caitlyn is still "proud" of her Olympics success, she admitted she used to worry it meant she would be "stuck" as her former self.

Piers said: "It's genuinely educational. It's not that big a deal", she added.

Speaking about being transgender, Caitlyn who is Piers Morgan's first ever transgender guest said: "Actually Piers we have a lot to talk about because I think you represent a lot of people out there who don't understand this issue and exactly what it is".

Jenner confirmed she's transgender in April 2015 after splitting from Kris in September 2014 following almost 23 years of marriage.
